Lambda Vega 900 Manuals

Vega 900 Handbook � Part Number 17155 NOMINAL INPUT VOLTAGE RANGE 165 - 240VAC MAX. INPUT VOLTAGE RANGE 150 - 264VAC INPUT FREQUENCY 47- 63Hz MAXIMUM INPUT CURRENT 9 A AC INRUSH CURRENT <40 AMPS Adjustment and Derating. The Vega 900 series is designed to provide a max output power of 900W at nominal output volt- ages. The following procedure must be used to ensure the PSU is operated within its ratings a Calculate user power for each module (volts x amps). b Add all the individual module powers together. The total power must not exceed the value given. c Calculate secondary transformer turns x amps for each module. See the outputs table for transformer secondary turns. d Add all the module turns x amps together and this must not exceed the ampere turns. e If necessary reduce the loading until the conditions are met, ie. power and ampere-turns maxima. Input Parameters Output Parameters Test requirements include: PSU to be fitted in its end-use equipment and operated under the most adverse conditions permitted in the end-use equipment handbook/specification and which will result in the highest temperatures in the PSU. To determine the most adverse conditions consideration should be given to the end use equipment maximum operating ambient, the PSU loading and input voltage, ventilation, end use equipment orientation, the position of doors & cov- ers, etc. Temperatures should be monitored using type K fine wire thermocouples (secured with cyanoacrylate adhesive, or similar) placed on the hottest part of the component (out of any direct airflow) and the equipment should be run until all temperatures have stabilised. Customer Air Cooling (option C): The following method must be used for determining the safe operation of PSUs when C option (Customer Air) is fitted, ie fan not fitted to PSU. For PSUs cooled by customer supplied airflow the components listed in the following table must not exceed the temperatures given. Additionally ratings specified for units with an internal fan must still be complied with, eg mains input voltage range, maximum output power, ampere turns, module voltage / current ratings and maximum ambient temperature. To determine the component temperatures the heating tests must be conducted in accordance with the requirements of IEC/EN/CSA60950-1:2001 Clause 4.5. Consideration should also be give to the requirements of other safety standards. Note 1:The PSU main transformer has three regions for module secondaries seperated by two primary windings. Starting nearest slot 1, region A, primary winding, region B, primary winding, region C. The total ampere turns (AT) in any two adjacent regions is limited to that in the table above column, “ Max AT in adjacent regions (note 1)”.See mains transformer regions table below for modules allowed in each region. The table uses module widths with a twin output module being single width. n/a=not applicable Main transformer regions table: * Ruggedised fan (Papst 622HH, not for use in PSU’s fitted with IEC inlet).
